try without catch in BlockStackingLM.getNextKnuthElements

[Vincent Hennebert]

Hi,

Could anybody explain me what is the purpose of the following piece of
code:
    if (!breakBeforeServed) {
        try {
            if (addKnuthElementsForBreakBefore(returnList, context)) {
                return returnList;
            }
        } finally {
            breakBeforeServed = true;
        }
    }
that we can find, for instance, in BlockStackingLM.getNextKnuthElements?

Isn’t it equivalent to the following:
    if (!breakBeforeServed) {
        breakBeforeServed = true;
        if (addKnuthElementsForBreakBefore(returnList, context)) {
            return returnList;
        }
    }
Maybe I’m missing something obvious...


Thanks,
Vincent
